Your firefox 22 screenshot is loaded completely different html templates. The other stuff looks css related (which gets cached). So it is possible, theres something on our end serving old templates. Will bug dave/marcel about it.

Clearing the cache does not change anything. It happens only on the front page, and the news part of Neowin (neowin.net & neowin.net/news/*). The icons in the forums part (neowin.net/forum/*) are displayed properly next to the username.

I have emptied and quit Safari twice, just in case. Things are better, but I still get this :

As you can see Firefox is now displaying the icons properly compared to last time.

Safari seems to have some problems still. Those two squares on the far right appear when I hover above the location of the Messenger and Notifications icons. That is better than the first screen shot that I posted.

It is still only affecting the front (neowin.net) and news (neowin.net/news/*) pages only, forums (neowin.net/forum/*) are fine, no display problem there.
